Description

[Detailed Description of the Invention] This invention relates to the structure of a holder suitable for use when attaching electrical components such as light emitting diodes to electrical equipment.

Conventionally, as shown in FIG. 1, as a structure for attaching an electrical component such as a light emitting diode to an electrical device such as a receiver, an electrical component 3 such as a light emitting diode is installed in a hole 2 formed in a front panel 1 of the electrical device. At the same time as the head is inserted, the electrical component 3 is fixed to the same panel 1 by the adhesive prefix 4, and the lead terminal 5.5 of the electrical component 3 is inserted backward through the hole 7 of the sub-chassis plate 6 arranged at the rear of the front panel 1. It is known that the lead terminals 5, 5 are made to protrude, and lead wires are connected to the lead terminals 5, 5 by soldering or the like.

By the way, according to this electrical component mounting structure, when adhering the electrical component 3 to the front panel 1, it is necessary to fix the electrical component 3 in a predetermined position by appropriate means until the adhesive hardens. This has the disadvantage that the installation work of the electrical component 3 is troublesome, and furthermore, since the electrical component 3 is directly glued to the front panel 1, if the electrical component 3 breaks down, it is necessary to use the hardened adhesive part when replacing it. This has the disadvantage that the electrical component 3 cannot be replaced in practice.

However, the applicant proposed a mounting structure for electrical parts that eliminated the above-mentioned drawbacks, as shown in FIG.
No. 598 (Utility Model Application Publication No. 53-116278).

That is, in the mounting structure shown in FIG. 2, an electrical component 3 such as a light emitting diode is mounted on a board 8 such as a printed circuit board, and the board 8 is mounted on a mounting frame 9 made of an elastic material such as rubber (the detailed shape of which is shown in FIG. 3). ), and the mounting frame 9 can be attached and detached between the front panel 1 and the sub-chassis plate 6 disposed behind it by inserting the head of the electrical component 3 into the hole 2 of the front panel 1. The electrical components 3 are wired via terminals 10 and 10 attached to the board 8.

According to this electrical component mounting structure, since the electrical component 3 can be removed from the front panel 1 and the sub-chassis plate 6 of the mounting frame 9, it can be replaced together with the board 8 if the electrical component 3 breaks down.

However, in the mounting structure shown in FIG. 2, if an error occurs in the mounting position of the sub-chassis 6 to the front panel 1 and the dimension between them exceeds the specified dimension, the front panel 1, the sub-chassis 6 The mounting state of the mounting frame 9 on the mounting frame 9 and the mounting state of the electrical component 3 on the mounting frame 9 are unstable, and there is a drawback that the electrical component 3 cannot be mounted reliably.

In addition, in this mounting structure, since the electrical component 3 is directly attached to the board 8, it is difficult to remove the electrical component 3 from the board 8, and when replacing the electrical component 3, the board 8
It also had the disadvantage of being uneconomical as it had to be replaced as well.

This idea was created in view of the above circumstances, and its purpose is to easily and reliably attach electrical components such as light emitting diodes to electrical equipment such as receivers. The object of the present invention is to provide a holder for electrical parts that can be attached to a holder and that allows easy replacement of the electrical parts.

A pair of leg portions 20 and 20 extending downward from 8 and 18 are integrally molded.

In this case, the arm portion 19°19 and the leg portion 20.20 have engaging protrusions 21.21.
22.22 is formed.

This holder A is made of synthetic resin such as nylon, and has elastically deformable parts, including a retaining wall 16 located at both ends of a connecting wall 17, a mounting wall 18, and a mounting wall 18. The two parts consisting of the arm part 19 and the leg part 20 are connected to each other with the center point p of the connecting wall part 17 as the center.

The two parts consisting of the arm part 1 are centered around the mounting wall part 18.
The distal ends of the legs 9, 19 and the legs 20, 20 can integrally rotate in directions toward and away from each other.

Further, as shown in FIG. 7, the light emitting diode B includes a rectangular plate-shaped base 25, a square column-shaped light emitting part 26 formed on the upper surface of this base 25, and is attached to the base 26 so as to protrude downward. It consists of a lead wire 27°27.

Next, a method for attaching the light emitting diode B to an electrical device using the holder A formed as described above will be described.

FIG. 8 and FIG. 9 are diagrams showing an example of the mounting method. As a method for mounting the light emitting diode B in the hole 31 of the front panel 30 of an electrical device, the light emitting diode B is mounted on the holder A, and the light emitting diode B is mounted on the holder A. FIG. 4 is a diagram showing an example in which holder A is attached to a printed circuit board 32, and the printed circuit board 32 is attached to a front panel 30.

When installing light emitting diode B as shown in these figures, first insert the base 25 of light emitting diode B between the arms 19 of holder A by expanding them to point P, and then insert the base 25 of light emitting diode B between them. The base 25 is located between the projections 21.21 of the arms 19, 19 and the respective tips of the respective tips 16.16 of the retaining walls 16, 16.

When expanding the arms 19, 19, the arms 19, 19 themselves may be held and expanded;
9. Since the legs 20 can move integrally, the legs 20.
The arm portions 19° 19 can also be expanded by grasping the arms 20 and deforming them so that their tips are close to each other.

In this case, the lead wires 27.27 of the light emitting diode B are passed through both sides of the connecting wall 17 of the holder A to the leg portions 20.20.
Extend in the direction in which it extends.

In this state, the light emitting diode B is clamped by the elastic restoring force of the arms 19, 19, with its base 25 being restricted in its vertical position by the oil holders 21, 21 and the retaining walls 16, 16, and held in the holder A. Reliably held.

Then, the holder A with the light emitting diode B attached thereto is attached to the printed circuit board 32.

That is, the legs 20.20 of holder A are connected to the printed circuit board 32.
Insert the leg portion 20.20 into the hole 33.33 formed in the hole 33.33 while expanding it around point P, and bring the lower surfaces of the mounting walls 18, 18 into contact with the upper surface of the printed circuit board 32 so that the protrusion 22° 2
2 is engaged with the lower surface of the substrate 32.

In this case, the lower end of the lead wire 27 of the light emitting diode B is passed through the electrical component mounting hole 34, 34 and connected to the printed circuit board B.
cr) It is made to protrude in the F direction and positioned so that it can be soldered to a wiring conductor (not shown) formed on the lower surface of the same board B.

In this state, the holder A is regulated in its vertical position by the mounting wall 18.18 and the protrusion 22.22, and the leg 2
It can be reliably attached to the printed circuit board 32 with an elastic return force of 0.20.

Here, the holding force with which holder A holds light emitting diode B and the holding force with which holder A holds printed circuit board 32 are due to the cooperative action of arms 19, 19 and legs 20, 20 of holder A. It is.

That is, the legs 19.19 are slightly widened by the insertion of the light emitting diode B.

This means that the distal ends of the legs 20.20 are brought closer to each other, since the arms 19 and legs 20 of the - pair work together, and the legs 20.20 are connected to the printed circuit board 30. This results in an increase in the power to prolong the process.

Further, the leg portion 20.20 is connected to the hole 33.3 of the printed circuit board 32.
3 and are expanded by engaging within.

Therefore, this results in an increase in the force with which the arm portions 19, 19 hold the light emitting diode B, contrary to the above.

As a result of holding each part in this manner, the holding of the light emitting diode B and the attachment of the holder A to the printed circuit board 32 become extremely reliable.

In this way, if the light emitting diode B is mounted as described above using the holder A, the holding force for the light emitting diode B and the mounting force for the printed circuit board 32 can be easily ensured. Even if there is a dimensional error in the holding part and the mounting part, there is an advantage that this error can be sufficiently absorbed.

After assembling the light emitting diode B, holder A, and printed circuit board 32 in this way, the bottom surface of the printed circuit board 32 is immersed in a solder bath and the lead wires 27 and 27 of the light emitting diode B are assembled.
and the wiring conductor of the printed circuit board 32 are soldered.

In this case, the base 25 and the light emitting part 26 of the light emitting diode B
is attached to the printed circuit board 32 via the holder A.

It is spaced a predetermined distance from the printed circuit board 32 and is hardly affected by heat during soldering.

Next, this assembly is attached to the light emitting part 2 of light emitting diode B.

One substrate 32 is attached to the support pillars 36 and 36 by screws 35 and 35.
and attach it to the front panel 30.

Wiring to the light emitting diode B thus attached to the front panel 30 is performed by connecting the lead wires on the electrical equipment main body side to the wiring conductors of the printed circuit board 15.

According to the mounting structure of light emitting diode B using holder A as described above, if light emitting diode B breaks down and needs to be replaced, for example, only light emitting diode B can be easily replaced. can do.

In other words, when replacing, first, light emitting diode B,
The assembly of holder A and printed circuit board 32 is attached to front panel 30.
Remove from.

In this state, the base 25 and the light emitting part 26 of the light emitting diode B are separated from the substrate 32, so that the base 25 and the light emitting part 26 are
5. Even though the light emitting part 26 is gripped and removed from the holder A, the soldered lead wires 27 and 27 can be easily removed from the board 32.

After replacing the light emitting diode B with a new one, the assembly can be reattached to the front panel 30.

In the above usage example of holder A, holder A was attached to the electrical equipment side, that is, to the front panel 30 via the printed circuit board 32. It may also be attached to a sub-chassis or the like disposed within the device.

Further, the electrical components to be attached using the holder according to this invention are not limited to the light emitting diodes described in the above embodiments, but may be various display elements, changeover switches, etc.

As is clear from the above explanation, the holder of this invention uses elastic return force to hold the electrical components and attach them to the electrical equipment, so the electrical components can be easily and reliably attached to the electrical equipment. There is an advantage that it can be done.

In addition, it is possible to easily secure the holding force for the electric component and the force for attachment to the electric equipment side, and there is an advantage that dimensional errors of the holding part and the attachment part of the electric part and the electric equipment side can be sufficiently absorbed.

In addition, if this holder is used, for example, when attaching electrical components to a printed circuit board, the electrical components can be wired while being separated from the printer I/board, which makes it easier to replace the electrical components. There are advantages.
